Should've put this in mathematics, you know? But don't worry, mistakes happen!
Though, in order to do this problem, we need to add 20 for the total gallon.
Let's use X for a placeholder to determine the amount, as the gallon of 25% alcohol and percentages can be in decimal forms. It'd be 0.25x gallons worth of alcohol afterwards. We then add 20-x gallons to 5% of alcohol, which is 0.05(20-x).
This would then allow us to find the sum of 20 gallons to 20% of alcohol, containing at least 0.2(20) gallons of the alcohol.
We'd then be able to develop this equation;
0.25x + 0.05(20-x) = 0.2(20).
And then so on the sequence continues...
0.25x + 1 - 0.05x = 4
0.2x = 3
x = 3/0.2
We'd then be able to come to a conclusion that;
1. X equals 15 gallons of 25% alcohol
2. 20-x equals 5 gallons of 5% alcohol.
Sustainable use practices are practices that are used in the use of resources for example that seek to maintain the longevity and continuance of the potential use of that resource. In regards to trees and logging the sustainable use of wood or paper would seek to continue the longevity and vitality of the forests by not overusing these products. Sustainable use will use a resource at a rate that will allow for natural replenishment or incremental use of the resource to prevent harm to the environment and allow the resource to be used far into the future.
Answer:
B
Explanation:
The Space Shuttle was a partially reusable low Earth orbital spacecraft system operated from 1981 to 2011 by the National Aeronautics and Space Administration (NASA) as part of the Space Shuttle program.Its official program name was Space Transportation System (STS), taken from a 1969 plan for a system of reusable spacecraft where it was the only item funded for development.
Answer:
cause rocks to break and move
are older than surrounding rocks
Explanation:
Faults are form of fractures which occur in rocks as a result of variety of conditions such as mechanical and temperature changes. Faults forms cracks and leave spaces between rock parts.
They usually cause rocks to break and move and are older than surrounding rocks which validates the options
